Check
The illustration shows adjustment of the 1st front axle. Adjustment procedure for the 2nd front axle is analogous.
1 | Position the projector (5) on the projector support (4). |
2 | Turn the wheel to the right on the rotating plate (3) by angle (a). |
a = 20° |
3 | Put the projector (5) in the horizontal in the longitudinal direction and tighten the wing screw (16). |
4 | Turn the rotating button (29) until level (30) is centered. |

5 | Place the scaled disc (32) in position 0 for later measurement. |
6 | Turn the wheel to the right on the rotating plate (3) by angle (a). |
a = 20° |

7 | Place the projector in the horizontal position. |
8 | Turn the rotating button (29) until level (30) is centered. |
9 | Read the value indicated on the scale disc for caster measurement (32) (e.g.: 4°). |
The scaled disc for caster measurement (32) is divided in measuring sections "positive caster" and "negative caster". The "positive caster" measuring range is 0 to +15°. The "negative caster" measuring range is 0 to -3°. One division on the scaled disc represents 10'. |
10 | Record the measuring value on the alignment form.. |
11 | If these values are not reached, adjust caster. |
12 | Repeat the same procedure for work steps 1 to 11 on the other wheel of the 2nd font axle. |

Adjust
13 | Support the axle to prevent falling. |
14 | Remove spring clamps (6). |
15 | Lift and support the chassis frame. |
16 | Remove wedge (7) and install the selected wedge. |
The wedges are available in several angles |
17 | Lower the chassis frame, making sure the pin fits correctly into the hole of the wedge. |
18 | Install spring clamps (6). |
Replace self-locking nuts (8). |
19 | Repeat the caster check. |
